ROPE-CLAMP.

Application filed May 25, 1918.

To all whom it may concern Be it known that I, REINHOLD Loos, a citizen of Russia, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Rope-Clamps, of which the following is a full, clear, and exact specii'ication.

This invention relates to clamps especially designed for securing a rope, and has for its object to provide a device or" this kindwhich is of simple construction, inexpensive to manufacture, may be easily and quickly assembled and taken apart, and which will automatically increase its grip upon the rope as strain is exerted on the latter. Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views Figure 1 is a side elevation of the clamp with ropes attached.

Fig. 2 is a plan view of the same.

Fig. 3 is a central longitudinal section taken vertically through the clamp as shown in Fig. l, and

Figs. 4 and 5 are detailed perspective views of the two members of the clamp separated.

The clamp is composed of only two pieces which are not connected by any fixed pivot pin, as is usual in such devices, but have a pivotal connection when assembled for use which is equivalent to a pivot pin in action but is of advantage over such pivot pin in that the parts of pieces of the clamp may be more quickly assembled and taken apart, and there is no danger of a pivot pin working loose and dropping out when the clamp is in use.

The member of piece 1 of the clamp is angular in form, having a base portion 3 and a handle. portion 4 extending upward at an obtuse angle thereto. The base portion 3 has a longitudinal slot 5 extending from near its free end to the bend where it joins onto the handle portion and beyondl Specication of Letters Patent.

free end ot the base portion the slot is widened out and preferably rounded, as at 5 to permit the shank 7 of the other member or piece 2 of the clamp to be rotated therein when the two members are being assembled.

rihe member 2 of the clamp is substantially straight and has yat one end of its shank 7 an eye portion S which is wider than said shank and is adapted to have a rope 14 connected thereto, as illustrated in Figs. 1, 2 and 3. At the other end of the shank there is a broadened latportion 9 withoppositely projecting edges 10 extending at right angles to said shank and adapted to form a pivotal connection between the member 2 and the member 1 when the shank of member 2 is arranged in the slot 3 of member 1, as shown best in Fig. 3. The pivotal edges 10 are preferably beveled or sharpened, as at 12, to make their action easier, and it will be seen that when the members of the clamp are assembled, said edges engage the member 1 near the bend therein at opposite sides of the end portion of the slot 3 where it extends slightly beyond said bend and into the handle portion 4.

On the under tace of the flattened portion 9 of the member 2 there is formed a downwardly extending angular lug 110 having an inclined face 11 and adapted to fit laterally between the walls of the slot 5 in the member 1, so as to prevent the members of the clamp lfrom twisting laterally with respect to one another. The free end of the attened portion 9 has an angular notch 13 therein which comes above the outer end portion of the slot in the member l, said flattened portion overlapping said slot, so that when a rope 15 is passed upwardly through said slot, as illustrated, it will be clamped between the end of the slot and the inclined face 11 of the lug 110 and the angle of the notch 13. Strain upon the rope l5 after it has been engaged with the clamp will tend to draw the flattened portion and lug of the member 2 more securely down upon the rope because of the tendency of the two-members ot the clamp to straighten out and of the frictional contact between the rope 15 and the beveled or inclined tace 11 of the lug 110 and the notch 13. `When it is desired to release the rope 15 from the clamp it is only necessary to exert upward pressure on the handle 4 which will cause the .slotted end of the member l to move away from the notched end of the member' 2, thus removing the grip of the clamp from the rope. Y Having thus described my invention, what I claim as new and desire to secure bv Letters Patent of the United States is l. A rope clamp comprising two members, one having a slot and the vother a shank to fit said slot, there being means for connecting a rope to'one end ot the second member and a broadened portion at' the other end of the shank with oppositely extending edges to pivotally engage the lirst member lat the end of the slot therein, and means at the free end of said latt'ened'portion for clamping a rope in 'the other end 'of the slot.

2. A ropeV clamp comprising two members, one having a slot and. the other a shank to fitl in saidV slot, means` at one end of the shank-` for'V connecting` a rope thereto, a broadenedportion at' the other end of the shank: with oppositely extending edges to pivotally' engage the iirst lmember at the endV of the' slot therein, and a notchy in the free end of said. broadened portion for grip ping a rope passed through the slot.

3. rope clamp comprising two members, one having a slot and the other a shank to fit in said slot, means at one end of the shank for connecting a rope thereto, a broadened portion at the other end of the shank with oppositely extending edges to pivotally engage the irst member at the end of the slot therein, and a downwardly extending lug on said. broadened portion to iit in lessees ened portion at the other end of the shank with oppositely extending edges to pivotally engage the iirst member at the end of the slot therein, a downwardly extending lug on said broadened portion to fit in said slot and having an inclined tace to clamp` a rope which is passed through thel slot, and a notch in the end of said broaden-ed portion for also gripping the rope which is passed through the slot.

5. A rope clamp comprising two members, one being angular in form and having a base portion and a handle portion. at opposite sides of' the bend, there being a slot in the base portion and extending past the bend into the angular handle portion, the other member having a shank to extend through the slot in the iirst member, means at one end of the shank Jfor connecting a rope thereto, a broadened portion at the other end of the shank with oppositely extending edges to pivotally engage the first member adjacent the bend therein, and means on the free end of the second member for clamping a rope passed through the slot in the first member.

In testimony whereof l have signed my name to this specification.
